Cloned bovines have a much higher abortion rate than those derived in vivo. Available evidence indicates that inappropriate epigenetic reprogramming of donor nuclei is the primary cause of cloning failure. To gain a better understanding of the DNA methylation changes associated with the high abortion rate of cloned bovines, we examined the DNA methylation status of a repeated sequence (satellit...

The Pontifical Academy for Life published a response about the moral legitimacy of immunizing children with vaccines manufactured using cell strains derived from aborted human fetuses. In order to fully appreciate the level of cooperation involved among different agents, it is important to review the history of the development of these cell strains: “The need to articulate a moral reflection on...

Trisomy 9 is a rare chromosomal abnormality with a very poor prognosis depending mostly on the amount and exact location of the duplicated genetic material. Most of the fetuses with complete trisomy 9 are spontaneously aborted in the early first trimester and therefore it is uncommonly seen at the time of 11-14 weeks’ scan. The diagnosis is usually made after fetal karyotyping performed for rou...

Ewe abortion and neonatal mortality are serious problems to sheep farmer. The objective of this paper was to report isolation of Erysipelothrix rhusiopathiae from aborted fetuses in a flock in Tehran, Iran. Abortion occurred in 10% of ewes in the flock. The fetuses were well developed and pinpoint, necrotic-like lesions were recorded on the placental cotyledons, whilst the inter -cotyledonary a...

The promise of transactional memory is to make concurrent programming tractable and efficient by allowing the user to assemble sequences of actions in atomic transactions with allor-nothing semantics. It is usually expedcted that transactional memory must ensure that all committed transactions constitute a serial execution respecting the real-time order. In contrast, aborted or incomplete trans...

Between February 1995 and June 1999, specimens from seven aborted bison (Bison bison) fetuses or stillborn calves and their placentas, two additional placentas, three dead neonates, one 2-wk-old calf, and 35 juvenile and adult female bison from Yellowstone National Park (USA) were submitted for bacteriologic and histopathologic examination. One adult animal with a retained placenta had recently...

Surgical neuroangiographic procedures (therapeutic embolizations) in the head and neck are often complicated by vascular spasm, particularly in external carotid artery branches. Numerous methods to relieve spasm have been attempted, including intraarterial administration of nitroglycerin, papavarine, contrast material, and lidocaine [1 , 2]. Local infiltration with procaine has also been used [...

OHMANN, H. BIELEFELDT: Immunoglobulin levels in non-aborted and aborted fetuses from Danish herds of cattle. Acta vet. soancl. 1981, 22, 428-434. The applicability of serological tests in the diagnosis of intrauterine infections in Danish cattle was investigated. Fetuses from slaughter animals, experimentally infected and spontaneously aborted fetuses, premature and stillborn calves, were subje...
